Extremely Active Severe Weather Pattern (June 19-22)

Although June is typically an active month of severe weather for south central Nebraska and north central Kansas, much of the area dealt with one round of severe weather after anotherduring the 4-day period between Saturday, June 19th - Tuesday, June 22, 2010.

Dozens of reports of damaging winds, large hail, flooding rainfall, and even a few tornadoes were received during this time. The main culprits for this multi-day onslaught of severe weather and flooding were a nearly stationary surface front draped near the Nebraska-Kansas state line, and a persistent train of low pressure systems moving in from the western United States. As seen in the "interactive" map of storm reports below, the majority of severe weather during this time targeted north central Kansas, and also portions of south central Nebraska along and south of I-80. Most locations north of I-80 within the NWS Hastings coverage area were spared widespread coverage of severe storms.

Severe Weather:Here are just a few of the "highlights" of the June 19-22 period, based on a multitude of reports received from storm spotters, local law enforcement/emergency management, and storm chasers:

June 20: EF-2 tornado in Superior, NE, with winds estimated up to 120 MPH

June 19: EF-1 tornado near Randall, KS, with winds estimated up to 100 MPH
